基于pycomm3包的Ethernet/IP协议的python实现 Ethernet/IP(EIP)协议的通信python实现，用pycomm3包进行支持。 Ethernet/IP 协议可能要求包含的功能：隐式报文通信、显示报文通信 (Explicit 讯息通信)、支持UCMM 及Class3 如果您需要创建Ethernet/IP协议的自定义实现，则通常需要研究Ethernet/IP规范、处理低级套接字通信、消息编码和解码、消息的组装和拆解以及各种其他特定于协议的细节。这是一项复杂的任务，需要对网络协议和编程有扎实的理解。在大多数情况下，建议使用现有的库或工具来节省时间并确保可靠的通信。 Ethernet/IP 协议的从头实现比较复杂，但是也有相关的库可以调用。比如 python 的 pycomm3。 pycomm3库抽象了许多Ethernet/IP协议的复杂性，但是了解协议的概念和结构对于有效地使用库并排除可能出现的任何问题仍然很重要。 Here’s a basic example of how you might use it to communicate with an Ethernet/IP device: $ pip install pycomm3 #====== python通信代码：========= from pycomm3 import LogixDriver # Create a LogixDriver instance with LogixDriver('192.168.1.100') as plc: # replace '192.168.1.100' with the actual IP address of your device # Read tag values tag_values = plc.read('Tag1', 'Tag2') # adjust the tag names and values as needed # Write tag values plc.

Sumerizing: The ways and implementations for assigning wifi passcode to ESP32/ESP8266 MCU Assigning WiFi pass code to ESP chip is ubiqutous. To summerize, we can do it with ways listed below: AP mode: A web running on chip, Chip working as Station mode. Bluethooth. (ESP8266 has no bluetooth moduel.) ESP Touch App with ESP smartConfig© solution. (5G Hz is not supported.) others, such as AP-STA link by routers, AP by cellphone, wifi manag-frame broadcasting. Comparations with methods above: Tech Methods UserConfident SuccessRate Popularity softAP Mode middle High High SmartConfig High Low High Bluetooth High High middle (esp8266 has no BLE) Ps: ESP32:Update Wi-Fi Credentials Using Bluetooth Application, link

Let me share some thoughts bout creating academic research paper. How to find the innovative ideas for a new paper A new idea is believed by the newbee PhD student a precious seed for his/her paper. And the papers are believed as their lifesaver for their tough days. Solution: a. adjust the mindset. A book named as ‘phD grind’ written by Philip Guo may helps. b. In your research area, hack up a classical work, a hot research work, a gorgeous work or a work you just want to hack up.

How to use LittleFS on ESP32 with vsCode+platfromIO As a suplement of this tutorial How to use LittleFS on ESP8266 I follows some reference and examples to build this blog. Get to konw some basic introductions about SPIFFS and LittleFS on ESP8266 and ESP32 is necessary for a noob. Note: Most of the functions for SPIFFS operations are compatible for LittleFS. follow the tutorials one by one: - SPIFFS for ESP8266 - SPIFFS for ESP32 - LittleFS for ESP8266 - LittleFS for ESP32 LittleFS is newly introduced into ESP32 SDK (Aug 2021) .

Install Fail2Ban On CentOS 7 Posted on December 13, 2019 by David Singer What Is Fail2Ban? Fail2ban is an open-source software that actively scans the servers log files in real-time for any brute force login attempts, and if found, summarily blocks the attack using the servers firewall software (firewalld or iptables). Fail2Ban runs as a background process and continuously scans the log files for unusual login patterns and security breach attempts. Installation In order to install Fail2Ban on CentOS 7, we first need to enable the EPEL (Extra Packages for Enterprise Linux) repository.

Fixing certbot does not know where nginx is located in your server If your certbot cannot auto configure ssl for your host: The cause of this problem Mine is because the installation path of nginx is not the default one， such as /etc/nginx or /usr/bin/nginx When Certbot is unable to automatically configure your web: Follow the GPT’s answer: ME: Certbot doesn't know how to automatically configure the web server on this system. GPT: If Certbot is unable to automatically configure your web server, it usually means that it couldn't identify the web server software and configuration on your system.

import esp-idf components: import the components is easy: git clone , mkdir <proj_dir>/components, and copy into <proj_dir>/components The git repos and commands that I used for this testing: git clone https://github.com/natanaeljr/esp32-I2Cbus.git I2Cbus git clone https://github.com/natanaeljr/esp32-MPU-driver.git MPUdriver mkdir -p <proj_path>/components mv I2Cbus <proj_path>/components mv MPUdriver <proj_path>/components for more, refer: https://github.com/natanaeljr/esp32-MPU-driver Do sdkconfig for the right chip and protocal for the imported component if the hello_world_main.c is renamed, rename it in <proj_dir>/main/CMakeLists.txt
